How-to China: Magic grass spreads prosperity and peace overseas

Q: Could you tell us a little bit about some difficulties you faced while promoting this technique in Papua New Guinea 20 years ago? How did you overcome these difficulties?

The biggest obstacle we faced was when we were teaching this technique to locals in the Eastern Highlands (Papua New Guinea).

We kept simplifying the technique to make it easier for the locals to pick it up.

I have a picture here.

It's a sterilization device made from three petrol cans. It can match the sterilization efficiency of an oil-fired boiler, but costs just 800 yuan ($125), as compared to traditional sterilization methods that cost more than 100,000 yuan.

It is also safer. There is no need to train locals to handle boilers, which is a highly professional skill set.

Besides, it is portable and can be moved from one village to another once the work is done.

We also taught the breeding technique to locals on site, which has achieved good results after nearly 20 years of efforts.
